TO ALL WHOM IT MAY CONCERN:

Be it known that I, WILLIM L. SANDISH, of Pittsburg, in the' county ofAllegheny, and State of Pennsyl- Vania, have invented a new and usefulimprovement in Machinery for Making Bunge, Plugs, Taps, 86o.; and I dohereby declare that therfollowing ,-is a full, clear, and exactdescription thereof, which will enable others skilled in the art to makeand use 'the same, reference being had to the accompanying drawings,forming part of this specification, in which-Y l i Figure l is aplan ofmy improved combined automatic machinery forA cutting and compressingbungs, plugs, taps, ttc.

Figure 2 is a vertical longitudinal section, taken in the line z a, fig.1.

Similar letters of reference indicate like parts.

The nature bf this invention consists in constructing and combiningmechanieal'devices for making bungs,'

plugs, taps, ttc., for barrels and other purposes, and consists of ahollow cutter, tapering on the inside, worked by'a slide on a guide-pinrunning through it, by which the. Wood blocks are cut and compressed onthe points, in connection with which cutter are feeding devices, and acircular saw for cutting olf the blocks to form the bungs, plugs, ortaps from a strip of wood, which blocks are presented successively infront of the hollow cutter, and are released therefrom'by the guide-rod,on which the cutter moves back and forth, to be discharged afterA theyare cut and finished ready for use, (all of which operations areperformedautomatically with greatprecision in the movements of themachinery, producing superior bungs, plugs,i'taps, &c.,with a greatsaving of labor.

A is a frame for supporting Vthe machinery. B is the driving-shaft,actuated by steam or other power, and provided with a ily-wheel, on oneend of which shaft-is a pinion, a, engaginga large spur-wheel a', placedon the upper shaft l ,`that carries an eccentrichC, for moving the mainslide D, on the top of the frame, withy the cutter c at one end madefast to the cutter-head c by'a set-screw. The cutter c is made hollow,of one piece` of steel bored out, with two opposite projecting points orlips, to cut gradually and prevent the fracture or splitting of theblocks, and 'they are made with a sharp edge on the inside by a bevel onthe outside. The back end of the bore is made tapering or cupped, togive the proper taper shape'to the bungs, ttc., by compression..

A guide-pin, c?, passes through the cutter, and islmade fast at the rearend to a cross-bar, cZ, fixed on the frame.

The front end extends nearly to a guide-bar, E, in which is a holeopposite the end of the cutter,through-` which it passes to cut theblocks in the box, which are backed by the fla-t face ofa round die, e,set in a chuck, F, which the cutter passes over` and which is set on theframe to bear against the bung when it is cut, and force it into thehollow of the cutter for the purpose of compressing the point, in ataper form. The guide-box E receives and guides the blocks successivelyin front of the cutter c, after they have been cut from a strip of Woodby the circular saw G, on the arbor h, which is hung in a sliding-frame,H, connected by the rod g with the main slide D, and actuated by apulley, I, on the drivingfshaft B, belted to the pulley I on acounter-shaft, B', that drives a pulleyl, belted to a small pulley, J',on the saw-arbor 7L, as seen in tig. 1. The'connectingrodg is providedwith a spiral spring, g', to guard the saw against accident in case ofthe belt slipping or breaking, and the rod ,g is made adjustable by ascrew on the end toregulate the reciprocating movement of the slide withthe saw. The strip of wood is fed by a ratchet-wheel, lc, placed underthe bed-frame, worked by a pawl, k1, connected with the saw slide-frameH, and borne into the teeth of the ratchet-wheel by a spring, n, and thestrip passes between two feed rolls, k2 k3, on the upper side of thebed, one of which rolls, k2, is on the arbor of the ratchet-wheel, whilethe feed-roll 7c3 is pivoted on aslide, m, that draws it up by means ofa weight and pulley below the bed, to press againstl the strip of woodand bear it upon the feed-wheel k2, but a spring may be employed for thesame purpose. Between the feed-rolls and the guide'box E is a guide-way,E, for the strip of wood to pass through in front of the saw, to be cutinto blocks, which/are pushed on into the guide-box, to be cut by thecutter into bungs. l t l The operation is' manifest: The strip of wo'odis moved up by the. ratchet-wheel the proper distance for cutting orf ablock by the saw, which comes up to the work with the slide I-I, whenthe main slide D moves back after the cutter c has cut the bung by theforward movement of the slide, actuated by the eccentric C. The

snow 2 bung, plug, or tap, when cut, remains in the hollow cutter, andis withdrawn by it from the guide-box E until it strikes the end of theguide-pin d, which then lpushes it out and discharges it finished.

Having described my invention, I claim as new, and desire to secure byLetters Patent- 1. The hollow taper steel'cutter c, the guide-pin CZ,the guide-box E, and the die e, constructed, eombined,`

and operating substantially as and for the purposes herein described.

2. The combination of the saw Gr, and the sliding-frame H and D,constructed and operating substantially as and for the purpose hereinspecified.

3. The ratchet-Wheel lc and pawl k1 in combination with the feed-rollsc2 k3, and the slide-frame H, arranged and operating substantially asand forv the purpose specified. i

4. 'lhe combination of the hollow cutter c, the guide-pin d,the-guide-box E, the die e, the sew G', the ratchet c, the feed-rolls czk3, and the slides D and II, or the equivalents of them or either ofthem, when combined and organized substantially as described for cuttingthe blocks and pointing or tapering the ends of bun s luvs, or ta s inthe manner specified. v
